Other than completing a CAPTCHA (tips for completing these here) these sites are free and simple to get free Bitcoins.
To make things easier and quicker for you links open in a new window, so click the link, collect your free coins, close the window and repeat.

These faucets are validated daily for your convenience, if you find one that doesn't work however please let us know.

My personal faves are Alien Bitcoin (pays on average 4x more than any other faucet) and Moon Bitcoin (just because you can open it and let it run).Standalone Sites
These sites work without a third party micro transaction site, they often keep a record of your earnings and payout either weekly or whenever you reach a specific limit.Moon Bitcoin - allows you to claim every 5 minutes, but the reward increases the longer you leave it)Coin Check In - allows you to claim random amount every 5 minutesThe Red Bitcoin - free roulette lets you place a chip every 2 minutesAlien Bitcoin - lets you claim a random amount every 10 minutes (can claim over 2000 satoshi every hour).Pocket Dice- Fun dice game.

Coinbox.me Network

These are coinbox.me network sites, when you grab the free bitcoins from these they send the payment to coinbox.me who keep it safe until you reach 0.00005500 BTC then they send the payment to you. You can always look at www.coinbox.me at any time to see how many coins you have accrued.

FaucetBox
A smaller bitcoin wallet network, like all other wallet networks, simply log into FaucetBox to view your current balance. It has one of the highest payout levels, so it will take a while for your Bitcoin payout to end up in your account.
